I remember when you asked people to suggest perks some time ago, but I don't think anyone suggested anything, apart from yourself about those increasing storage in https://www.totemtribe.com/bugs/view/anti-starving-mechanism-in-case-of-internet-electricity-issue/ .
That being said, you can already make those shown as "NOT WORKING": Assassin, Surveillance, Demolitioners (while other perks are not very good, this one would be insane and easy to implement), Insightful (no idea what "additional information here and here" would be but could be fun), War of the Worlds (could be interesting, people with big armies could still be damaged by people with more culture), Disarm (no description but we guess what it would do, "Double strike" too maybe), Phoenix Rising (sounds interesting too, especially if it could allow an army that would normally be completely be destroyed, to still come back home with a few units and the Colorado stripes it earned), Egghead (good additional science points, I don't know what would be the exact differences with "Economy of science" though), and Golden Horde (I'm thinking mainly that it would be good with stealth attacks since, unless enemy hero is in catacomb/subway, it's unlikely that the hero would be in the attacked town, and thus it could make attacks with stealth fighters/special agents decent because right now they are terrible).
So as you can see, you can do a lot already, just like you did years ago with enlightened, whirlwind etc, you can make a lot of perks without doing all of them.
